Application filed August 25,1;921) Serial no. 495,213.

To all whom it may concern:

Be it known that I, STINER' T. HniiensoN, am a citizen of the UnitedStates, residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in Adjustable Metal Frames; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to frames especially adapted for window screens,doors, glass panels and the like, and more'particularly to such framesthat may be adjusted to difierent sized openings and thereafter havingattached thereto a screen or glass panel.

To the above end, generally stated, the invention consists of thenoveldevices and combinations of devices hereinafter described anddefined in the claims.

In the accompanying drawings, whidh illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is an inside perspective view of one form of the invention;

Fig. 2 is an outside elevation of the same;

Fig. 3 is a fragmentary perspective View in section taken on the line 33of Fig. 2, on an enlarged scale;

Fig. 4 is a view corresponding to Fig. 1, but showing a slightmodification;

Fig. 5 is a view principally in longitudinal section taken on the line5-5 of Fig. 2, on an enlarged scale;

Fig. 6 is a detail view with some parts sectioned on the line 6-6 ofFig. 1; and

Fig. 7 is a fragmentary perspective view in section showing a furthermodification of the invention.

Referring first to the invention as shown in Figs. 1, 2, 3, 5 and 6, thenumeral 8 in dicates, as an entirety, a rectangular metal framecomprising four tubular right angle sections arranged in duplicate pairs9 and 10. Duplicate frame sections are located at diagonally oppositecorners of the frame 8 of different sizes.

and the legs of the frame sections 9 are telescoped into the legs of thesections 10 with freedom for sliding movement, which permits the frame 8to be adjusted both horizontally and vertically to fit openings The legsof the frame sections 9 and 10' are polygonal in cross section andclosely fit, theone within the other, so as to firmly hold the framesections. Formed in the outer faces of'the legs of the frame sections 9and 10 are channels 11 in endless arrangement and the channels ofconnected legs have dove-tail interlocking sliding engagement, as bestshown in F 3.

' The telescopically connected legs of the frame sections 9 and 10 areadjusta-bly connected by staples 12, the prongs of which are seated inholes in the bottoms of the channels 11 in the legs of the frame 10,with freedom for endwise movement into and out of any of a plurality oflongitudinally spaced holes 13 in the bottoms of the channels 11 in thelegs of the frame sections 9, as best shown in Fig. 5.

The invention, as shown, also includes a screen panel 14, which, afterthe sash is adjusted to an opening and the sections thereof connected bythe staples 12, has its marginal portions pressed by any suitable tool,which securely attaches said panel to the frame, as best shown in Fig.3. WVhile the frictional engagement of the staples 12 with the holes inwhich they are mounted is suflicient to hold the same in operativepositions, the same are further securely held in operative positions bythe overlying screen panel 14. After the panel 14 is once attached tothe frame 8, said frame cannot be again adjusted without removing thepanel therefrom.

As one means for detachably securing the improved frame to stops 15,only one of which is shown, I provide a plurality of latch plates 16having in their edges, near one of their ends, opposite lock notches 17,and having in one of their edges, near the other end thereof, a locknotch 18. The latch plates 16 are adapted to be inserted endwise intotransverse lock slots 19 in the legs of the sash sections 9 and 10 andthen turned to cause the lock notches 17 to interlock with said legs. Inthis position of the latch plates 16, they extend parallel to the stops15 and headed studs 20, one of' which is shown in Fig. 6, in the form ofa wood screw, are inserted through the lock notches 18 and then screwedinto the stops 15. When the latch plates 16 are thus secured to a stop,they cannot turn in the lock notches 19 and securely hold the frame inposition.

Referring now to the construction shown in Fig. 4, the frame 21 is madeup of four right angle frame sections, each of which comprises rigidlyconnected-legs 22mm 23.-

r The sections of the'frame 21 arev identical,

' the one with the other, and the legs 22 are 'telescoped into thelegs23 forsliding ad 7 justment;

The construction shown in"-Fig. 7 is the same as that shown in Fig.3,With the exception that channels 24 are formed in the frame-sections 9and 10 to receive a glass panel 25. .A "pliable joint strip .26 isinterposed bettveenthe channels 24 and; panel a The above described 25to formtight" jointsl' A Weather strip 27 is formed on theouter'edges'of the frame sections 9 and 10 and is adapted to be seatedin. an endless slot in themember in which the frame is mounted. f i

invention, While eX t remely simple and of comparatively small cost tomanufacture,is thought to be highly efficient for the purpose had inView. What I claim is:

1. A tubular frame the body of Which I is'closed and has pressed fromone of its faces a channel that is Within said body and dove-tail incross section, said body and channel'being continuous in cross section,and a screen panel, the marginal edge portion of which is pressed andfolded into the channel to 7 form a self-interlocking joint With. theframe to secure the screen panel thereto. 7 a V 1 2. A tubular framemade up offour right angle sections, the legs of'whichrareetele i 35 ingcontinuous in cross s'ect'ion,a nd ascreen. panel, the marginal edgeportion of which 7 is pressed and folded. into the exposed cportions ofthei channel sections toforrna selfinterlocking joint with'theframe tosecure the screen panel thereto.

, In testimony whereof 7 I aflix 'my signature.
